Phonological and phonetic impairment in aphasic speech: an acoustic study of the voice onset time of six French-speaking aphasic patients.
Phonological and phonetic impairment in aphasic speech: an acoustic study of the voice onset time of six French-speaking aphasic patients. Clin Linguist Phon. 2019 May 30;:1-21 Authors: Verhaegen C, Delvaux V, Fagniart S, Huet K, Piccaluga M, Harmegnies B Abstract The aim of the present study is to contribute to the description of the speech production deficits in French-speaking aphasic patients, so as to shed light on their potential phonetic and/or phonological disorders. Acoustic studies of aphasics' speech productions remain relatively infrequent, especially in French, and when entering into the specifics, often lead to inconsistent results. We conducted a multiple-case study on six aphasic patients, four with non-fluent aphasia and two with fluent aphasia. They were administered a variety of language and neuropsychological tasks, then they participated in a customized non-word repetition task. Acoustic analyses of their speech productions were performed, focussing on VOT as the main acoustic correlate of the voicing contrast for oral stops. Other atypicalities in their productions were also classified. Results showed variable and mainly "mixed" phonetic-phonological impairment profiles that differed from the traditional hypotheses made in the literature about the speech deficits to be expected as a function of type of aphasia. Our results support the use of acoustic analyses in order to complete language examination in aphasic patients bu...

ConclusionSSRI therapy did not improve disability and QOL in multi-ethnic Asian patients with first-ever stroke undergoing rehabilitation.
A 27-year-old male presented to the emergency department with altered mental status well as aphasia, lethargy, and dizziness that developed over the previous two days. His family denied any recent seizure-like activity, loss of consciousness, nausea, vomiting, or fevers.
We described a case of PACNS initially misdiagnosed as glioblastoma. The patient was a 35 year-old female with right-sided weakness and expressive dysphasia. Brain MRI showed a tumor-like lesion highly suggestive of glioblastoma, therefor surgical removal was done. After a resection and an exhaustive workup, PACNS was ultimately diagnosed. The case illustrates a type of imaging presentation of PACNS that is often misdiagnosed as high-grade glioma. Differentiation between tumor-like PACNS lesions and actual CNS tumors is challenging due to similar MR images. To avoid unnecessary surgical interventions, we summarized previou...
(Medical University of South Carolina) Researchers at the Medical University of South Carolina (MUSC) and elsewhere report in Brain that the left lateral temporal cortex must be intact in stroke patients with aphasia if they are to have their speech entrained. In speech entrainment, stroke survivors practice fluent speech production by following along with another speaker. The efficacy of this experimental approach for certain patients with non-fluent aphasia will be assessed by an MUSC-led multi-site trial.
Conclusion: For the purpose of delirium screening in patients with aphasia, increasing the ICDSC cut-off value to ≥ 5 points enables effective screening. Further studies are necessary to characterize post-stroke delirium.
